I have an awsome idea with a lot of post-production but 1-month is not enough time. Take a pic of a site that is about 1/3 to 1/2 complete, then take another at the end. Creative cutting and pasting to make the final product have area's of incomplete mixed with it.

hiking mike - that reminded me one pinhole photography - a few days (months? ) exposure, with details coming from the bare pilons to the finished building. It looked pretty awesome, but i cant remember where did i saw this picture.
